To all whom it may concern;

Be it known that I, GEOR E F.; Bnoz a citizen ofthe United States, residing in the city and county of Honolulu, inthe Terri;

,tory' of Hawaii, have invented a new and I useful Improvement in a Joint Aeraton'of which the following is a specification. I

My invention relatesto improvements in skewers wherein a perforated tube operates in conjunction with a pointed rod arranged to be inserted therein to form a. skewer to be inserted within a joint of beer or the like, to aerate said jointftoprevent souring of the same. I The primary object of thepresentfinven- ,tion is to provide a new and improved skewer arranged to thoroughly aerate-the joint and the inner portion of thethicker portion of a hind quarter of beef, to prevent souring thereof.

Another object of the present invention is to provide a new and improved skewer ofthe character described which may be easily inserted within a joint of beef toaerate the same.

A furtherv object of thepresent invention is to provide a new and improved device of the type set forth having means forretaining an open channel throu'gh a joint'of beef in order to permit the free and unobstructed passage of air therethrough to facilitate the passageof animalheat from said joint.

I accomplish these and. other objects by means of the improved device describedin the drawings forming apart of the present specification, wherein likecharacters of reference are used to designate similar parts throughout the said specification and draw-f ings, and in which Fig. 1 is a representation of I quarter-of beef disclosing my inventionapplied thereto; f r

Fig. 2is aside elevation of Figure l disclosing the skewer inserted "through the thicker portion of the beef 9 Fig. 3 is, an enlarged, broken view, partly in section, disclosing the invention assembled for insertion through the joint;

is used to designate in general a hinda I hind-- within asuitable refrigerator, whereby the quarter of beef. dressed for the market.. After dressing the beef theseveral quarters are moved into-andfstored, for a'period,

animal heat may be removed from thef'rneat for preservation purposes. 1; i I

The joint wherethe rear ori hindleg is 1 jointed to the pelvisis the*thiekerfportion ,of-the meat and long after other portions have cooled (and the animal heat. has been.

removed or radiated therefrom this inner.) portion around the joint is still warm and containsconsiderableportion of animal heat. 1

Unless :this heat is I thoroughly and completely removed from the beef what is known to, the trade as sour joint results:

and the meat is sp'oiled.. w

. "In order to facilitate the reniOValbfILZthis heat] from the joint: and-expose the same 3 more readily to the surrounding atinopshere p -t I have invented what I terma join-t aerator "which consists principally of tube 2 providediwith perforations or- "apertures .3

throughout, substantially,-.the entire length of said tube-2. One end of the tube 2 is I M tapered .as at?) while theoppoSite end is providedwith a lateral extension t,j'the,pur
